Well, lets drop the universe having a center thing... Although,
the

exact

place in space and time where the big bang "was called into
existence"

could

arguably be the center? Na...

Since the big bang filled the entire universe, not just some part of
it,
that center would be everywhere.


While I can agree with the conclusion (or that there is no well
defined
centre) I can't agree with the logic. Just because air fills an
entire
balloon doesn't mean that the centre is everywhere.

How can you have a center if there is no boundary? And there was no
space and time until the big bang, or until the Lord said "let there
be
light" depending on your preference.

While I don't have any argument with the cosmology i feel I must
nitpick.
Consider the ball (x,y,z) with x²+y²+z² < 1. This ball doesn't not have
a
boundary, at least not that is part of the ball. But it does have a
centre.
So you can most definitely have a centre without a boundary.

I must also nitpick about 'until', a concept that only exists after the
big
bang.

Peter

That ball most certainly has a boundary, in that x=y=z =1 (or 2 for that
matter) is outside the ball. So if you are playing semantic games by the
fact that the "boundary doesn't exist because < allows infinitesimals.
bah.

Now, point at the region outside the universe, in three space.
